high speed vertical machining centers are a kind of sheet metal processing, providing molds, shell parts. When drilling, milling, boring and other processing operations are completed, but its high price, and processing consumption are much higher than traditional hand-operated machine tools, so the need for machining centers can be significantly reduced with single-item processing. Therefore, machining center design has a deep relationship between its machining efficiency and quality. How can the design of high speed vertical machining centers be more standardized?

1. Higher static and dynamic demeanor
The cost of high speed vertical machining centers is high, and the cost of loss during processing is much higher than that of traditional machine tools. This requires the machine tool to be able to greatly shorten the processing time. For this problem, there are currently two ways to go. One is that the change in the development mode of tool materials has greatly improved the cutting speed, which has doubled the cutting time; the other is that the automatic tool change system is used to achieve the effect of quick tool change and quick clamping. The adoption of these important measures has greatly improved the company's production efficiency, enabling machine tool owners to obtain good economic and environmental benefits.
2. Better static stiffness
For a high speed vertical machining center, the structural rigidity of its components such as bed, table, headstock, guide rail, etc. is closely related to the accuracy of the machine tool, so these factors all require the machine tool to have relatively high static stiffness. In the cutting process, there will be inevitable vibration, which will affect the machining accuracy and surface quality, and also reduce the tool life, which has a significant impact on the production efficiency. The machining center works continuously for a long time, and the vibration reduction in the machining cannot be eliminated by human intervention adjustment. Therefore, the dynamic stiffness of the machine tool needs to be improved.
3. Smaller thermal deformation.
When the cutting machine is executed, without exception, heat will be generated, which will affect the anti-machine, the machine tool, and cause the components to produce different degrees of thermal deformation, which will affect the precision of the processed product. How to affect the heat dissipation problem of the processed products is a slow decline in accuracy that has to be considered. At present, we can improve the structure of the machine, and the machine lacks thermal deformation of deformation in the direction we can control. E.g. Using a double-column frame structure, a symmetrical, thermally deformed horizontal machining center column that translates the lift axis in the axial direction can also be compensated by correcting the coordinates to reduce heat generation and extrude the host as far as possible from the heat source separation.
4. The friction between the moving parts is small and the clearance of the transmission control system is eliminated
The movement of the working platform of the machine tool takes the pulse equivalent as a small unit. When carrying out tooling or other slow operations, the worktable is required to respond accurately to the commands issued by the CNC system, which is related to the friction of the moving parts.
5. Long life, good precision retention
For the development of high speed vertical machining centers, having your own set of perfect lubrication management system design is a very guarantee for the life of the machine tool, so it should be selected when selecting machine tool guide rails, spindle components, screw rods, etc. The more wear-resistant materials enable the enterprise processing service center to maintain good precision for a long time.
6. Humanized design
In order to save the time of clamping and changing the tool, high speed vertical machining centers usually use multiple tool holders and automatic tool changing devices, so that one clamping can solve more problems. Therefore, in the process of tool clamping and tool changing, manual intervention is minimized to make the human-machine interface more clean and tidy. The improvement of the interlocking ability with the machine tool can also effectively reduce the occurrence of accidents. At the same time, the setting of the emergency stop device can effectively avoid the occurrence of accidents, and all operations are concentrated in one panel, which is more conducive to operation.
